Re: Coosa Composites.

The product gets mentioned here occaissionaly. I am not sure there has been a resto thread yet. It seems a bit pricey, so that is why you find most folks using wood.

Re: Coosa Composites.

I've not gotten any firm prices yet, but you could be right. One guy I talked to said he charges $500 a day plus materials. Another guy who does wood had given me a firm price of $800 for a transom replacement. that price was just the transom work and not including engine/outdrive removal and prep for the transom work.

Re: Coosa Composites.

I restored my 1995 Larson 214 LXI using all composites. Nida Bond for the stringers (pourable compound) and 1/2" Coosa Bluewater 20 on the deck. The Coosa is a bit pricier than wood, but considering you use less resin and cloth, the cost difference isn't extreme. However, I had a somewhat local source for the material so didn't have to pay for transportation (call Coosa and they can find you a local dealer). I forget the price/board, but believe my restoration project was only a few hundred dollars over the cost of using wood. This was well worth it in my mind as rot becomes a non-issue. Plus, there is the added benefit of reducing the weight.

Coosa is easier to work with than plywood. It cuts and shapes using conventional tools - although you will go through several jigsaw blades. I do advise wearing leather gloves when handling it as there are real tiny fiberglass particles created when cutting which can be quite irritating to the skin. I laminated both sides of the deck, however Coosa staff told me that typically only the walking surface needs to be glassed.

My only complaint is its ability to hold a screw. No problem adhering the deck to the stringers, but screwing the seats to the deck is a different story. What I did was epoxy stainless steel threaded inserts into the Coosa. This took some time, but worked well and allows for easy removal and put-back of all components attached to the deck.

If I can find some pictures I'll post them. Using Coosa (and Nida Bond), was definitely worth it to me.

Re: Coosa Composites.

thanks Ben. that kinda goes along with what my local guy said. he said he likes to glass a mounting plate (wood I assume) to the coosa for attaching seats.

Re: Coosa Composites.

I had my 23' Wellcraft CC transom redone with coosa instead of ply some years ago. Kinda expensive but you never will have to do it again so worth the extra $. I was told that coosa is used for the transom core on off shore unlimited race boats but I did not verify this.

Re: Coosa Composites.

I just had the transom and rear floor repaired at a shop. He used wood for the floors, but happened to have some Penske board left over from a larger job, so used that for the transom. I'm very pleased!
